One year ago, the Estonian government moved a war memorial honoring Russian-Estonians who died fighting the Nazis, a move that may have triggered what some believe is the first instance of a sustained, international cyberwar.

Now, Gadi Evron, a former Israeli Government CERT manager who was in Estonia at the time of the attacks, has revisited the events with an article in the Georgetown Journal of International Affairs and reprinted here online (PDF).

Evron said what could be described as a "flash mob" created the disturbances in the Estonian Internet during May 2007. "Not only did the … Read more

A distributed denial-of-service attack on Radio Free Europe/Radio Liberty this week is the latest attack in a resurgence of hacktivism (hacking + activism) in the Internet underground, a security researcher says.

The attack knocked out or interrupted eight RFL/RL sites, starting with Belarus and including Kosovo, Russia, and Azerbaijan, according to the news agency's Web site.

At one point the Web sites were getting up to 50,000 fake hits per second from other machines. The attack started on April 26, the 22nd anniversary of the Chernobyl nuclear accident and RFE/RL was going to be covering demonstrators … Read more

Two toolkits designed to help ordinary people participate in denial-of-service attacks against Western media have surfaced on the Internet, according to one researcher.

In a blog Tuesday, Jose Nazario of Arbor Networks says one of the toolkits is easier to use than the other though both are designed for "the masses." This isn't new, and toolkits such as these have been created for other political protests in the past.

AntiCNN.exe was the first of the two tools found on the Internet. Nazario reports that it opens a flood of HTTP connections and attempts to hurt the … Read more

Although CNN escaped a distributed denial-of-service (DDoS) attack planned for Saturday, the site has experienced either random outages or inflated response times over the last 72 hours, according to one Internet research company.

Netcraft reported Tuesday that during a three-hour period on Sunday morning, the CNN.com site was unavailable from its listening post in Pennsylvania. And on Monday, the site experienced inflated response times. CNN.com did suffer a minor DDoS last Thursday, but recovered by limiting access from certain geographic areas, mainly Asia.

Also on Tuesday, The Dark Visitor, a site that tracks Chinese hackers, said a downloadable … Read more

Several groups of Internet organizers plan to show on Saturday that they can mobilize patriotic Chinese Internet users and wield their influence worldwide against what they say is anti-Chinese media in the Western world.

The Dark Visitor, a site that tracks the activities of Chinese computer hackers, is reporting that a distributed denial-of-service (DDoS) attack on CNN.com is planned for 8 p.m. Beijing time, or 5 a.m. PT in the United States.

But the organizers themselves (Google translated page) appear to be waffling, and Jose Nazario of Arbor Networks reports that there has been little preattack activity … Read more

This week we've seen two Internet events that are more alike than dissimilar. On Wednesday, an Estonian court convicted a 20-year Russian for his part in last spring's distributed denial-of-service (DDoS) attacks on that nation. On Thursday, word of mounting DDoS attacks on the Church of Scientology spread. Ultimately, both events could have larger repercussions.

The attack on the Estonian Web sites was prompted by an Estonian government plan to move a statue and grave sites honoring Russian-Estonians who died fighting the Nazis. Gadi Evron of Beyond Security said at last year's Black Hat USA that he … Read more

A 20-year-old Russian has been convicted for organizing some of the attacks on Estonia's government sites during spring 2007, the Agence France-Presse reported on Thursday.

"Dmitri Galushkevich is the first hacker to be sentenced for organizing a massive cyberattack against an Estonian Web page," Gerrit Maesalu, spokesman for the regional prosecutor's office in northeast Estonia, told the AFP. Galushkevich was fined 17,500 krooni (about $1,600). He admitted his guilt, said Maesalu.

The distributed denial of service (DDoS) attacks, which some security experts have alternatively called a flash mob or the first-ever cyberwar, was prompted … Read more

Warning: disturbing a war memorial can provoke all out cyber war--at least in Estonia. On April 27, 2007, Estonia officials relocated the "Bronze Soldier," a Soviet-era war memorial commemorating an unknown Russian who died fighting the Nazis, a move that incited rioting by ethnic Russians and the blockading of the Estonian Embassy in Moscow. It also started a large and sustained distributed denial-of-service attack on several Estonian Web sites, including those of government ministries and the prime minister's Reform Party. A denial-of-service attack (DoS) occurs when someone directs a large number of requests to a target URL; … Read more
